Patent DE-3630157-A1 (DE)
Title: Process for purifying flux baths, such as are used in hot galvanising
IPC: C23C2/30
Filed: 1986-09-04
Abstract: Hitherto, the iron salts undesired in flux baths have been removed by precipitation as iron(III) hydroxide and subsequent filtration, for example by the Didier VFR process (German Patent 2,029,580). This process operates in the pH range between 3 and 5. Although the precipitation of the iron hydroxide takes place outside the flux basin, contamination of the basin contents by precipitated iron hydroxide, which is frequently also deposited on the bottom of the basin, is unavoidable. Since these iron compounds are also undesired, efforts are made to avoid their occurrence in the flux. The newly elaborated process avoids iron hydroxide in the flux by running the flux bath under conditions under which no iron hydroxide can appear. This is operated in a pH range below 3 in the flux bath. The precipitation of iron as iron(III) hydroxide takes place only at the anode in a treatment vessel during the action of direct current on the flux solution. By means of an appropriate design of the anode, the iron(III) hydroxide formed can be transported immediately after its formation from the anode region into the filter. In the cathode region, intensive movement of the bath must be ensured, so that the zinc precipitated on the cathode grows compactly thereon. The cathodes are changed as required and made re-usable by pickling.

IPC: H02M7/537
Filed: 1986-09-26
Abstract: A circuit is described for producing an alternating voltage in an electronic device which is remotely fed over a digital transmission path. By the pulses of a clock (8) two capacitors, C1, C2 are charged via a transistor (T1) and a transformer (10), one of them (C2) being discharged over a parallel resistor (R2). A coupling capacitor (CK) which is charged by the other capacitor (C1) is discharged alternately by the influence of the dischargeable capacitor (C2) over a transistor (T2).

IPC: G06T1/60
Filed: 1986-09-30
Abstract: The core of the invention is a data memory which can be used universally and which can be read under microprogram control without help from a higher-level computer. For image processing tasks, a freely programmable scan control in an image memory, not linked to a fixed row or column structure, can be implemented using the invention. In this way, image scenes can be searched quickly for specified image segments, for contour detection and pattern recognition purposes. The scan pattern can be preset by hard wiring, or loaded from (by) a higher-level computer into the microprogram memory, according to the application.

Title: Domestic gas connection apparatus
Inventor: JESCHKE IMMANUEL
IPC: F16L5/12
Filed: 1986-10-23
Abstract: The invention relates to a domestic gas connection apparatus, composed of a steel pipe which is to be laid in the building, of a plastic pipe which is to be laid in the earth and of a protective pipe which encloses the connection point of said two pipes, is to be installed in the building wall and projects outwards out of the building wall, in the case of which apparatus, at the connection point, a rubber sealing ring, which is pressed in the axial direction and rests on a supporting ring on one side, presses the plastic pipe on depressions of the metal pipe which has been pushed into said plastic pipe. The object which the invention is to achieve is to provide a domestic gas connection apparatus which is constructed only of a very small number of parts such that the assembly of the transition point steel pipe/plastic pipe can be carried out by the manufacturer, only a low outlay being required for the corrosion-protected configuration of said domestic gas connection apparatus. The invention achieves this object in that the rubber sealing ring rests, with its outer surface, on the protective pipe manufactured from steel, in that the protective pipe has, in its interior, a shoulder which is pressed axially against the rubber sealing ring, and in that the protective pipe is connected in a fixed and gas-tight manner to the steel pipe on that side of the connection point which is directed away from the plastic pipe.

Title: Sickness-certificate bonding machine
Inventor: ORDOWSKI EUGEN DIPL ING
IPC: B65C9/18
Filed: 1986-11-25
Abstract: By means of the sickness-certificate bonding machine, EDP-lettered adhesive labels are automatically bonded in the correct position with associated sickness certificates. The labels attached to a carrier paper are drawn over one edge of a plate, with the result that the labels are detached from the carrier paper and project above the upper edge of this plate to form a contact zone. The upper horizontal edge of the forms to be bonded is brought into this contact zone, and by switching on the drive of the carrier paper the label conveys the form mounted displaceably in a receptacle into the region of a roller nip of rotary-driven rollers, with the result that the two parts are bonded firmly to one another.

Title: Method for the rapid acquisition of spin resonance data for a spatially resolved examination of an object
Inventor: HAASE AXEL DR RER NAT
IPC: G01R33/54
Filed: 1986-12-19
Abstract: In the present method for rapid acquisition of spin resonance data for a spatially resolved examination of an object, in particular with respect to rapid NMR imaging (tomography), the data for the reconstruction of an image with an arbitrary spatial resolution are measured during the temporal duration of a spin resonance signal. In the method, at least one magnetic field gradient is varied at a relatively high frequency, which can lie between 1 kHz and 20 MHz, and samples of the spin resonance signal are measured at discrete instances at which the amplitude of all the gradients varied at the said frequency is 0. The frequency of the variation determines the maximum possible specimen scanning frequency of the SR signal, and the possible bandwidth. A further modulation of the amplitude of the gradient vibration produces a phase coding of the SR signal which permits a spatial assignment via a two-dimensional Fourier transformation. The method is possible in principle with each spin resonance experiment, in particular NMR experiment and each spin resonance signal, in particular NMR signal, resulting in the achievement of an arbitrary spatial resolution during the temporal duration of a single spin resonance signal, in particular NMR signal. The signal/noise ratio can be improved by averaging a plurality of spatially resolved SR signals over time. <IMAGE>

Title: Control devices for dérailleurs, in particular for bicycles
Inventor: NAUMANN HERBERT
IPC: B62M9/124
Filed: 1987-03-18
Abstract: Control devices for dérailleurs, in particular for bicycles, which are arranged in rear dérailleurs, front dérailleurs or shifters. The control devices convert a shifting movement, performed in only one direction by the rider, in both shifting directions in such a manner that the drive chain is moved, by an amount which is separately matched for each shifting step, beyond the shift positions and, after the drive chain rests on the sprocket wheel of a shift position, is brought back to the latter. By means of this automatically controlled sequence of movements, shifting operations can be carried out reliably and quickly by the rider without the rider delicately moving a shift lever back and forth for this purpose.

Title: Centrifugal speed governor for injection-type internal combustion engines
Inventor: JAHN WINFRIED
IPC: F02B3/06
Filed: 1987-06-29
Abstract: The invention relates to a centrifugal speed governor for injection-type internal combustion engines which is suitable only for controlling injection pumps in diesel engines. With the initial object of the invention being to create a governor having a small overall size and mass and a relatively simple design, the problem is to create a centrifugal speed governor which, despite the low mass of the centrifugal weights and the consequent flexibility of the control springs, achieves a functionally reliable control behaviour, particularly reliable maintenance of the zero-delivery quantity during propulsive operation and also when the engine is shut off. According to the invention the problem is solved because a throw-off lever is set by means of the operating lever in the zero-delivery position of this lever against the lever linkage in the zero-quantity direction, the main control spring being relieved by means of the operating lever for the lever linkage. <IMAGE>
